CentOS 7 安装 Zabbix Server 4.0

1. 关闭防火墙及 selinux

# systemctl disable firewalld
# systemctl stop firewalld
# firewall-cmd --state
not running
# reboot

# vi /etc/selinux/config

返回目录

2. 安装 Zabbix Server

参考链接：

https://www.zabbix.com/documentation/4.0/manual/installation/install_from_packages/rhel_centos

https://www.zabbix.com/download?zabbix=4.0&os_distribution=centos&os_version=7&db=mysql&ws=apache

1）ADDING ZABBIX REPOSITORY

# rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

2）FRONTEND INSTALLATION PREREQUISITES

# yum-config-manager --enable rhel-7-server-optional-rpms

如果遇到 yum-config-manager command not found，安装 yum-utils 后，再执行上一语句

# yum -y install yum-utils

如果1）、2）安装有问题，连接国外的服务器 repo.zabbix.com 经常连接失败，可参照 https://www.cnblogs.com/bruce-he/p/14385216.html

3）SERVER/PROXY/FRONTEND INSTALLATION

To install Zabbix server
# yum install zabbix-server-mysql

To install Zabbix proxy with MySQL support:
# yum install zabbix-proxy-mysql

To install Zabbix frontend (available for RHEL 7, deprecated on RHEL 6) with MySQL support:
# yum install zabbix-web-mysql

解决 mysql command not found

# ln -s /mnt/software/mysql/bin/mysql /usr/bin
# ln -s /mnt/data/mysql3307/mysql.sock /tmp/mysql.sock

备注：将 mysql 的bin 目录和 data的 sock 软连接到系统默认

4）Run the following on your database host.

# mysql -uroot -p
<password1>
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by '<password2>';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> flush privileges;
mysql> quit;

备注： password1为 mysql root用户的密码；  password2为设置的 zabbix 用户的密码

5）On Zabbix server host import initial schema and data. You will be prompted to enter your newly created password

# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

6）CONFIGURE DATABASE FOR ZABBIX SERVER/PROXY

# vi /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=<password>

7）STARTING ZABBIX SERVER PROCESS

# service zabbix-server start
# systemctl enable zabbix-server

8）ZABBIX FRONTEND CONFIGURATION

vi /etc/httpd/conf.d/zabbix.conf

php_value max_execution_time 300
php_value memory_limit 128M
php_value post_max_size 16M
php_value upload_max_filesize 2M
php_value max_input_time 300
php_value max_input_vars 10000
php_value always_populate_raw_post_data -1
php_value date.timezone Asia/Shanghai

9）SELINUX CONFIGURATION if Having SELinux status enabled in enforcing mode

# setsebool -P httpd_can_connect_zabbix on
If the database is accessible over network (including 'localhost' in case of PostgreSQL), you need to allow Zabbix frontend to connect to the database too:
# setsebool -P httpd_can_network_connect_db on

10）启动apache/zabbix-server服务并设置为开机启动

# systemctl start httpd
# systemctl enable httpd
# netstat -an |grep 80
tcp        0      0 192.168.56.11:80        0.0.0.0:*               LISTEN 
# systemctl start zabbix-server
# systemctl enable zabbix-server

返回目录

3. 配置 fronted

返回目录

4. 安装 Zabbix agent 并启动

安装zabbix agent
# yum install zabbix-agent

启动 zabbix agent
# systemctl restart zabbix-agent
# systemctl enable zabbix-agent

安装完待解决问题：图形显示不了，F12 提示 chart2.php 500 错误。后改为安装 Zabbix Server 5 没有问题（https://www.cnblogs.com/bruce-he/p/14381921.html）

返回目录

问题

1. Zabbix server is running, value = No

 # tailf  /var/log/zabbix/zabbix_server.log
  connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

解决办法：

# vi /etc/zabbix/zabbix_server.conf

   DBSocket=/tmp/mysql.sock

   备注： 配置 DBSocket

# systemctl stop zabbix-server
# systemctl start zabbix-server

2. Zabbix front php 配置有问题，需要重新配置时， http://ip/zabbix/setup.php

3. 安装zabbix之后登陆报错：Error connecting to database: No such file or directory

修改php.ini文件
[root@office_zabbix4_007117 etc]#vim /usr/local/php/etc/php.ini
添加一行：mysqli.default_socket = /mnt/data/mysql3307/mysql.sock
